Needs refactoring

[KleinerNull]

I was bored and looked into your code. I think it is not a good idea to write the complete code into the __init__.py.

I'd say one can split the _XMLDataset and the parse_using_profile code into seperate sub modules. So it can be easier to extend and change the code in the future.

After you'll have commited your actual changes I would refacture it for you, just don't want to mess with the merging problems now.

Agreed, I'm looking into your existing merge requests and feedback on the other areas, after that it should be easier moving forward with other merge requests. Closing this issue for now.
